This invention relates to a bathroom purification device used for disinfecting bathrooms.

To reduce the burden of cleaning bathrooms, particularly mold removal, it is common to spray disinfectant water containing disinfecting ingredients into the bathroom to disinfect and prevent the growth of mold and other contaminants. In recent years, bathroom purification equipment has been proposed that automatically sprays this disinfectant water into the bathroom.

For example, the bathroom purification equipment described in Patent Document 1 below is equipped with a sprayer for spraying disinfectant water into the bathroom (bathroom space), and as needed, the sprayer sprays disinfectant water onto the walls, ceiling, floor, etc. of the bathroom to disinfect and inhibit the growth of mold, etc.

JP 2010-227214 A

However, the conventional bathroom purification equipment shown in Patent Document 1 requires not only the installation of a sprayer in the bathroom, but also the installation of a piping system and pump to supply sterilized water to the sprayer, which requires a great deal of effort and time just for installation, resulting in increased costs. Therefore, conventional bathroom purification equipment has the drawback of being difficult and costly to install, making it difficult to use easily.

On the other hand, in the past, when spraying disinfectant water in a bathroom, there has been a strong desire to develop technology that can reliably spray high-concentration disinfectant water in order to achieve a high disinfecting effect.

This invention was made in consideration of the above-mentioned problems, and aims to provide a bathroom purification device that reduces installation effort and costs, is easy to use, and can reliably spray highly concentrated disinfectant water into the bathtub.

To solve the above problems, the present invention provides the following means.

[1] A bathroom purification device that purifies with disinfecting water containing a disinfecting component,
a portable device body to be installed in the bathroom;
a sterilized water storage tank provided in the device body and storing sterilized water;
an introduction section provided at the lower end of the sterilized water storage tank;
a jet outlet provided at an upper end of the sterilized water storage tank;
an introduction means for introducing push-up water from the introduction part into the sterilized water storage tank;
a swirling flow generating means for generating a swirling flow around the axis of the sterilized water storage tank with respect to the push-up water introduced from the introduction part,
This bathroom purification device is characterized in that the introduced push-up water swirls and rises in the disinfectant water storage tank, pushing up the disinfectant water, causing the disinfectant water to be sprayed out from the spray outlet.

[2] The introduction section has an outlet opening laterally at the center of the bottom surface of the sterilized water storage tank,
2. The bathroom purifying device according to claim 1, wherein the swirling flow generating means is constituted by a straightening plate that guides the upward flow of water flowing out sideways from the outlet in a swirling direction.

[3] The device body has an inlet for sucking in water stored in the bathtub,
3. The bathroom purifying device according to claim 1 or 2, wherein the sterilized water is produced using the accumulated water drawn in through the suction port.

[4] The bathroom purification device described in paragraph 3 above, which is configured to use the accumulated water sucked in through the suction port as boosting water.

[5] A bathroom purification device according to any one of paragraphs 1 to 4, wherein the device body is configured to be able to float in the water in the bathtub.

The bathroom purification device of invention [1] is equipped with a portable device body that is equipped with a spray outlet for spraying disinfectant water. This eliminates the need for extensive construction work such as installing a sprayer, piping, and a pump to spray disinfectant water inside the bathroom. Simply bringing the device body into the bathroom allows for easy disinfection of the bathroom and stored water, resulting in low cost, minimal effort, and significantly improved convenience. Furthermore, this bathroom purification device swirls the upward-moving water introduced from the bottom end as it raises the disinfectant water in the disinfectant water storage tank and sprays it out from the top. Therefore, the disinfectant water also swirls and rises in response to the swirling upward-moving water. The disinfectant water and the upward-moving water do not mix, and the two phases remain separate as they rise. This prevents a decrease in the concentration of the disinfectant water, ensuring the reliable spraying of highly concentrated disinfectant water, further improving the disinfecting effect.

The bathroom purifier of invention [2] uses a straightening plate to generate a swirling flow in the upward pressure water, which reliably generates a swirling flow and more reliably achieves the above-mentioned effects with a simple structure.

The bathroom purification devices of inventions [3] and [4] use accumulated water in the bathtub to generate disinfectant water and to use the accumulated water as boost water, eliminating the need to separately prepare disinfectant water or boost water, thereby improving convenience.

In the bathroom purification device of invention [5], the device body is configured to be able to float on the water in the bathtub. Therefore, by spraying disinfectant water while the device body floats and moves on the water, disinfectant water can be supplied evenly throughout the bathroom, further improving the disinfecting effect.

Figure 1 is a schematic plan view illustrating the installation state of a bathroom purification device according to an embodiment of the present invention. As shown in the figure, the bathroom purification device of this embodiment is configured to operate in two modes: a bathroom spray mode (bathroom spray mode) that uses pooled water (reserved bath water), such as leftover hot water in a bathtub 85, to generate hypochlorous acid water as disinfectant water, and sprays this hypochlorous acid water (electrolyzed hypochlorous acid water) into the bathroom space (inside the bathroom) to disinfect and clean surfaces within the bathroom, such as the ceiling, walls, and floor; and a pooled water disinfection mode that sprays electrolyzed hypochlorous acid water into the pooled water W to disinfect and clean the pooled water W. The detailed configuration of the bathroom purification device of this embodiment is described below.

As shown in Figure 1, the bathroom purification device of this embodiment basically comprises a device main body 1 installed inside the bathroom 8 and a remote controller (remote control) 5 installed outside the bathroom 8, such as in a dressing room (changing room) 9, and both the device main body 1 and the remote control 5 are portable types that can be carried around.

The remote control 5 is equipped with a cable with an outlet plug 51, and power is supplied to the bathroom purification device from a standard household outlet 91 into which the cable plug 51 is inserted.

The remote control 5 and the device main body 1 are connected by a power transmission cable 52, and power and control signals for driving each drive unit are sent from the remote control 5 to the device main body 1 via this conductive cable 52.

Figures 2 to 4 show the main body 1 of the bathroom purification device of this embodiment. As shown in these figures, the main body 1 of the bathroom purification device of this embodiment has a watertight casing 10, and when placed on the accumulated water W in the bathtub 85, it is configured so that it floats and moves freely along the water surface with a portion (lower portion) located below the water surface and the remaining portion (upper portion) located above the water surface.

The casing 10 comprises a plate-shaped base plate 11, a casing body 12 mounted on the base plate 11 and open at the top, and a lid 13 that closes the top opening of the casing body 12 in a watertight manner.

A circumferential groove-shaped recess (gap) 14 that opens outward is formed between the outer periphery of the bottom surface of the casing body 12 and the outer periphery of the base plate 11. Furthermore, an intake port 21 corresponding to the recess 14 is formed on the outer periphery of the bottom surface of the casing body 12. Although the intake port 21 actually opens downward, it is located within the recess 14 that opens to the side, so that the accumulated water W passes through the side opening of this recess 14 and is sucked into the intake port 21. In other words, in this embodiment, the accumulated water W is sucked into the intake port 21 from the side of the device body 1.

In addition, an outlet 22 is formed on the underside (bottom surface) of the base plate 11 of the casing 10, at a position offset from the axis of the casing 10 (device main body 1). This outlet 22 opens downward, and is configured so that the electrolyzed hypochlorous water generated inside the device main body 1 is discharged downward from the outlet 22.

Furthermore, a spray nozzle 23, the tip of which forms an outlet, is provided on the upper wall of the casing 10, and the electrolyzed hypochlorous water generated inside the device main body 1 is sprayed into the bathroom space through the spray nozzle 23.

In this embodiment, the suction port 21 and discharge port 22 are positioned below the surface of the stored water W (below the water surface) when the device main body 1 is floating in the stored water W, and the spray nozzle 23 is positioned above the surface of the stored water W (above the water surface). Note that the discharge port 22 does not necessarily have to be positioned below the water surface; sterilized water, described below, may be discharged from above the water surface and supplied to the stored water 23.

As shown in Figure 4, the casing 10 contains a flow sensor 25, a salt tank 26, a gear pump 27, and an electrolytic cell 3 such as a chlorine tank serving as a disinfected water storage unit (disinfected water storage tank). These devices, along with the above-mentioned suction port 21, discharge port 22, and spray nozzle 23, are connected by piping 4 as follows:

That is, the downstream side of the suction port 21 is connected to the flow sensor 25 via a piping path 4, and the piping path 4 downstream of the flow sensor 25 branches midway, with one branch path 4 connected to the salt tank 26 via a check valve 41 and the other branch path 4 connected to the gear pump 27 via a check valve 41. The other branch path 4 further branches and is connected to the discharge port 22 via a check valve 41. In other words, the upstream side of the gear pump 27 is connected to the discharge port 22.

The downstream side of the gear pump 27 is connected to the lower end of the electrolytic cell 3, and the downstream side (upper end) of the electrolytic cell 3 is connected to the spray nozzle 23.

The salt tank 26 is configured to store sodium chloride, such as table salt, inside, and can produce salt water by dissolving the salt in the suction water that passes through the tank.

The gear pump 27 is a pump capable of rotating forward and reverse. When rotated forward, it is configured to pump suction water such as salt water downstream to the electrolytic cell 3, and when rotated reverse, it is configured to reverse the suction water in the electrolytic cell 3 and pump it toward the discharge port 22 via the gear pump 27.

Figures 5 and 6 are a side cross-sectional view and a plan cross-sectional view showing the electrolytic cell 3. As shown in both figures, the electrolytic cell 3 functions not only as a reaction vessel that electrolyzes salt water to produce electrolyzed hypochlorous acid water, but also as a storage container (sterilized water storage section) that stores the produced electrolyzed hypochlorous acid water.

The electrolytic cell 3 does not have the same axis as the device main body 1, but is positioned at a location offset from the axis of the device main body 1. The electrolytic cell 3 comprises a cell main body 30 with a circular horizontal cross section that can store electrolyzed hypochlorous water, etc. An inlet pipe 31 is attached to the bottom wall of the cell main body 30 in a penetrating manner. The inlet pipe 31 is positioned on the vertical axis of the electrolytic cell 3, and is positioned so that its tip (upper end) protrudes into the interior of the cell main body 30.

A pair of outlet ports 32 that open in a direction perpendicular to the axial direction (toward both sides) are formed at the upper end of the inlet pipe 31. The lower end of the inlet pipe 31 is connected to the gear pump 27 via piping path 4, and as shown by arrow W2 in Figures 5 and 6, saltwater pumped under pressure from the gear pump 27 is introduced into the inlet pipe 31 and discharged in both directions from the outlet ports 32 at the upper end of the pipe.

The bottom surface of the tank body 30 is bowl-shaped (concave) with the deepest point being the center where the outlet 32 is located. The saltwater discharged to both sides from the outlet 32 flows outward and slightly diagonally upward along the concave bottom surface.

Furthermore, straightening plates 33 are provided on the bottom surface of the tank body 30, corresponding to both outlets 32. Each straightening plate 33 is formed in an arc shape when viewed from above, and the saltwater discharged from the outlets 32 is guided along the inner circumferential surface of the arc-shaped straightening plate 33, causing the saltwater to flow in a circumferential direction (around the axis), generating a swirling flow.

A plate-shaped electrode 34 is disposed at the bottom of the tank body 30, above the outlet 32 and the flow straightening plate 33. An outer peripheral gap 35 is formed between the outer peripheral edge of this electrode 34 and the inner peripheral surface of the tank body 30, allowing saltwater to flow through.

This electrode 34 also functions as a suppression plate that prevents the saltwater 2 discharged from the outlet 32 from rising directly. This function causes the saltwater to swirl and spread outward, rising through the outer peripheral gap 35. As a result, the saltwater rises while swirling along the inner peripheral surface of the tank body 30, filling the tank body 30. The reason for swirling the sucked saltwater will be explained later.

In Figure 6, the reference numeral "36" denotes a screw portion for fixing the electrode 34 to the tank body 30.

When the tank body 30 is filled with saltwater, a voltage is applied to the electrodes 34 by passing electricity through the tank, causing the saltwater to electrolyze, producing electrolyzed hypochlorous acid water (sterilizing water) whose main component is sodium hypochlorite.

The ceiling surface of the tank body 30 is dome-shaped (inverted bowl-shaped) with the center at the top, and an outlet 37 is formed in the center of the top surface. Furthermore, the above-mentioned spray nozzle 23 is attached to this outlet 37. In this embodiment, the spray nozzle 23 functions as the spray outlet (spray port).

The bathroom purification device of this embodiment is equipped with a control circuit (control device) (not shown). In response to an operation start command from the remote control 5, the control circuit controls the operation of the gear pump 27 and the supply of electricity to the electrode 34 based on information from various sensors, including the flow sensor 25, and timers, thereby enabling the device to selectively execute a bathroom spray mode and a pooled water sterilization mode, both of which are described in detail below.

First, place the remote control 5 for the bathroom purification device of this embodiment outside the bathroom 8, such as in the changing room 9, and insert the outlet plug 51 of the remote control 5 into a household outlet 91.

The device main body 1 is then floated in the remaining hot water W stored in the bathtub 85 in the bathroom 8. A predetermined amount of sodium chloride, such as table salt, has been placed in the salt tank 26 of the device main body 1 in advance. In this embodiment, an opening leading to the salt tank 26 is provided on the top surface of the device main body 1, and a cap 261 (see Figures 2 and 3) is attached to this opening. Therefore, by removing this cap 261, a predetermined amount of table salt can be placed into the salt tank 26 through the opening using a measuring spoon or the like.

After placing the device main unit 1 in the bathtub 85 in this way, close the bathroom door 81 if necessary (see Figure 1). In the bathroom purification device of this embodiment, the conductive cable 52 connecting the device main unit 1 placed inside the bathroom 8 to the remote control 5 placed outside the bathroom 8 is arranged to pass through the opening of the bathroom door 81, so when the door 81 is closed, it becomes pinched between the outer edge of the door 81 and the door opening edge 82.

In this embodiment, as shown in FIG. 7, the power transmission cable 52 is formed from a flat cable with a flat cross-section. As a result, as shown in FIG. 8, the power transmission cable 52 compresses and deforms the elastic packing (door packing) 83 at the door opening edge 82, allowing the power transmission cable 52 to be smoothly inserted and positioned between the outer peripheral edge of the door 81 and the door opening edge 82. Note that the two-dot chain line in FIG. 8 shows the elastic packing 83 when the door 81 is closed without the power transmission cable 52 installed.

In this embodiment, even if the power transmission cable 52 is placed in the door opening, the door 81 can reliably close the door opening in a sealed state, maintaining the bathroom 8 in a predetermined sealed state. Furthermore, no excessive load (stress) is applied locally to the power transmission cable 52 when it is pinched between the door 81 and the door opening edge 82, effectively preventing damage and deterioration of the power transmission cable 52 even over long periods of use, and ensuring the desired durability.

In this embodiment, in order to smoothly insert and position the power transmission cable 52 between the door 81 and the door opening 82, as shown in Figure 7, it is preferable to set the thickness A1 of the power transmission cable 52 to 1.0 mm to 4.0 mm and the width A2 to 6.0 mm to 10.0 mm.

After setting up the bathroom purification device of this embodiment in this way, a command to start operation in bathroom spray mode, pooled water sterilization mode, or other mode is given to the device main unit 1 via the remote control 5. In this embodiment, pressing and holding the push button on the remote control 5 starts the bathroom spray mode, and pressing it once briefly starts the pooled water sterilization mode.

For example, if you press and hold the push button to issue a command to start operation in bathroom spray mode, the device main body 1 will perform the following operations in response to that command.

That is, the gear pump 27 rotates forward, and the remaining hot water (pooled water) in the bathtub 85 is sucked in through the suction port 21. A portion of this suctioned water passes through the flow sensor 25 and is supplied to the salt tank 26, where salt is mixed in and dissolved, forming a sodium chloride solution (brine), which is then sent out. This brine and the suctioned water that bypasses the salt tank 26 combine to form brine of a predetermined concentration (primary brine), which is then sent to the gear pump 27. The gear pump 27 then sends this primary brine into the electrolytic cell 3. When the electrolytic cell 3 has been filled with a predetermined amount of primary brine, the gear pump 27 stops operating.

Then, electricity is passed through the electrode 34 of the electrolytic cell 3, and electrolysis of the primary brine begins within the electrolytic cell 3. After a predetermined time has passed, when sufficient electrolyzed hypochlorous water (sterilized water) W1 has been produced within the electrolytic cell 3 through electrolysis, electricity is stopped from passing through the electrode 34, and electrolysis is stopped.

When the electrolysis process is complete, the gear pump 27 rotates forward, and the remaining hot water is sucked in through the suction port 21, turning it into brine (secondary brine) W2 in the same manner as above, and is then sent into the electrolytic cell 3.

As shown in Figures 5 and 6, the secondary brine W2 pumped into the electrolytic cell 3 from the gear pump 27 is discharged to both sides along the bottom of the electrolytic cell 3, as previously described, and then guided by the straightening vane 34 to form a swirling flow around the axis and rise along the inner circumferential surface of the electrolytic cell 3. This swirling and rising secondary brine W2 pushes up the electrolytic hypochlorous acid water (sterilized water) W1 generated in the electrolytic cell 3, and the sterilized water W1 is supplied to the spray nozzle 23 through the upper outlet 37 of the electrolytic cell 3 and sprayed in the form of a mist from the tip of the nozzle.

In this way, the disinfectant water W1 is sprayed into the bathroom 8 space (bathroom space), and the disinfectant water W1 disinfects the entire bathroom, including the floor, walls, ceiling, windows, and drains of the bathroom 8, suppressing the growth of dirt such as mold and grease and significantly reducing the burden of cleaning the bathroom.

In this embodiment of the bathroom purification device, almost all of the sterilized water W1 in the electrolytic cell 3 is sprayed.

In this embodiment, when the disinfectant water W1 is sprayed from the spray nozzle 23, the disinfectant water W1 in the electrolytic cell 3 is pushed up by the swirling secondary salt water W2, so that the disinfectant water W1 also rises while swirling in response to the swirling of the secondary salt water W2. As a result, the disinfectant water W1 and the secondary salt water W2 do not mix, and the two phases of the disinfectant water W1 and the secondary salt water W2 rise in a separated state. This prevents a decrease in the sodium hypochlorite concentration (main component concentration) of the disinfectant water W1, and makes it possible to spray only this high-concentration disinfectant water W1. Therefore, the disinfecting effect of the sprayed disinfectant water W1 can be maintained high throughout, ensuring sufficient disinfecting effect.

In this embodiment, the secondary brine W2 constitutes the push-up water, and the gear pump 27 constitutes the introduction means. Furthermore, the straightening vane 33 constitutes the swirling flow generating means, and the introduction pipe 31 constitutes the introduction section.

In addition, in this embodiment, a circumferential groove-shaped recess (gap) 14 that opens to the side (outward) is formed between the casing body 12 of the device body 1 and the base plate 11, and an inlet 21 is formed within this recess 14. Therefore, when accumulated water W is sucked into the device body 1 through the inlet 21, the accumulated water W is sucked in from the side of the device body 1. This suction action causes the device body 1 to move in the opposite direction to the suction direction, so the device body 1 floats, moving slowly throughout the entire bathtub 85. Because the disinfectant water W1 is sprayed from the device body 1 that moves around in this way, the disinfectant water W1 can be sprayed evenly throughout the entire bathroom 8, further improving the disinfecting effect.

In addition, in this embodiment, the suction port 21 is formed in a recess 14 provided on the side of the device main body 1. Therefore, even if the device main body 1 floats and the side of the device main body 1 comes into contact with the wall of the bathtub 85, the opening of the recess 14 will be blocked by the bathtub wall, but the suction port 21 will not be blocked by the bathtub wall. This allows for stable suction of the accumulated water W, improving operational reliability and product quality.

Furthermore, in this embodiment, even though the power transmission cable 52 is passed through the door opening of the bathroom 8, the door opening can be reliably closed by the door 81. As a result, the bathroom 8 can be reliably kept sealed while the disinfectant water W1 is being sprayed, and the disinfectant water mist does not leak out from the door opening or the like, ensuring that the bathroom 8 is filled with the disinfectant water mist. This further reliably improves the disinfecting effect of the disinfectant water.

After spraying of the sterilized water W1 has finished, the secondary salt water W2 in the electrolytic cell 3 is discharged as needed. That is, the gear pump 27 rotates in the reverse direction, and residual water such as the secondary salt water W2 remaining in the electrolytic cell 3 flows back and is supplied to the gear pump 27 via the inlet pipe 31 of the electrolytic cell 3, and this residual water is then returned from the gear pump 27 to the bathtub 85 via the outlet 22. When the residual water in the electrolytic cell 3 has been returned to the bathtub 85 in this way, the bathroom spray mode is completed.

On the other hand, when using the stored water sterilization mode, the device main body 1 with salt added to the salt tank 26 is placed in the bathroom as described above. In this case, the door 81 to the bathroom 8 does not necessarily have to be closed and can be left open.

In this state, press the push button on the remote control 5 once briefly to issue a command to start operation in the stored water sterilization mode.

In response to this command, the gear pump 27 of the device main body 1 rotates in the forward direction as described above, and stored water W is sucked in through the suction port 21 as in the bathroom spray mode described above. After salt water (primary salt water) is filled into the electrolytic cell 3, the salt water is electrolyzed to produce electrolyzed hypochlorous acid water (sterilized water) W1.

Then, the gear pump 27 rotates in the reverse direction, causing the sterilized water W1 in the electrolytic cell 3 to flow backward, pass through the gear pump 27, and be discharged from the outlet 22 into the water W in the bathtub 85.

In this way, the sterilized water W1 is discharged into the water W stored in the bathtub 85, and the stored water W is sterilized and purified by the sterilized water W1.

When all of the sterilized water W1 in the electrolytic cell 3 has been discharged into the stored water W, the stored water sterilization mode is completed.

In this embodiment, the electrolytic cell 3 is positioned away from the axis of the device main body 1. Therefore, when sterilized water W1 is supplied into the stored water W and the amount of sterilized water W1 in the electrolytic cell 3 decreases, the weight of the entire electrolytic cell 3, including the sterilized water W1, decreases, and the center of gravity of the device main body 1 changes. As a result, the device main body 1 tilts and oscillates above the stored water W in the bathtub 85, causing the sterilized water W1 discharged from the discharge port 22 to be discharged in random directions. This allows the sterilized water W1 to be dispersed and supplied into the stored water W, and the sterilized water W1 can be mixed in while the stored water W is being stirred, allowing all of the stored water W to be sterilized evenly and without bias, further improving the sterilization effect.

Furthermore, because the discharge port 22 is positioned away from the axis of the device main body 1, the device main body 1 also vibrates due to the discharge force when the disinfecting water W1 is discharged from the discharge port 22. In this respect, the disinfecting water W1 can be dispersed in various directions, stirring the stored water W while being discharged, ensuring that the entire stored water W can be disinfected evenly, further improving the disinfecting effect.

As described above, the bathroom purification device of this embodiment can operate by simply floating the portable device main unit 1 in pooled water W, such as leftover bathwater in the bathtub 85, and operating it. This allows for two modes of operation: a bathroom spray mode in which disinfectant water W1 is sprayed into the bathroom 8 to disinfect the floor, walls, ceiling, etc., and a pooled water sterilization mode in which disinfectant water W1 is mixed into the pooled water W to sterilize the pooled water W. Therefore, the bathroom purification device of this embodiment does not require extensive construction work such as installing a sprayer for spraying disinfectant water, or spraying piping and pumps, etc., in the bathroom. Simply by bringing the device main unit 1 into the bathroom, you can easily disinfect the bathroom and pooled water, such as leftover bathwater, at low cost and with little effort, resulting in significantly improved convenience.

Furthermore, in the bathroom purification device of this embodiment, the device main body 1 that sprays disinfectant water floats freely on the accumulated water, so disinfectant water can be supplied evenly throughout the bathroom, achieving sufficient disinfecting effects. Similarly, disinfectant water can be mixed evenly into the accumulated water in the bathtub, further improving the disinfecting effect.

In particular, in this embodiment, as previously described, the device main body 1 is oscillated and moved due to the suction force of the accumulated water W from the suction port 21, the discharge force of the sterilized water W1 from the discharge port 21, and weight changes due to a decrease in the sterilized water in the electrolytic cell 3. This allows the sterilized water to be sprayed and discharged evenly and without bias, further improving the sterilization effect.

Furthermore, in this embodiment of the bathroom purification device, salt is mixed into the accumulated water W drawn from the bathtub, and the resulting saltwater is electrolyzed to produce disinfectant water. This means that operation can be started simply by adding salt, eliminating the need for the cumbersome task of separately preparing disinfectant water and storing it in a tank, for example, thereby further improving convenience.

In addition, the bathroom purification device of this embodiment can operate in two different modes (sterilization): a bathroom spray mode, which sterilizes the bathroom by spraying sterilizing water into the bathroom space, and a pooled water sterilization mode, which sterilizes the pooled water by supplying sterilizing water into the pooled water. This allows for sterilization tailored to the application, making it highly versatile.

Furthermore, in this embodiment, when the disinfectant water W1 in the electrolytic cell 3 is pushed up and sprayed by the secondary salt water W2, the secondary salt water W2 is swirled. As a result, as described above, the disinfectant water W1 and salt water W2 rise separately without mixing, ensuring that only high-concentration disinfectant water W1 is sprayed, preventing the release of low-concentration disinfectant water W1 due to the inclusion of salt water. Therefore, the disinfecting effect of the sprayed disinfectant water W1 can be maintained at a high level, and the disinfecting effect can be further reliably improved.

For reference, in an experimental example using the bathroom purification device of this embodiment, the concentration of sodium hypochlorite in the sprayed disinfectant water was measured in the first half of the spray (when the electrolytic cell 3 was almost filled with disinfectant water) and in the second half of the spray (when the disinfectant water in the electrolytic cell 3 was just about to be replaced by secondary salt water).The concentration in the first half was 23.26 ppm and the concentration in the second half was 15.16 ppm, and no significant decrease in concentration was observed from the first half to the second half of the spray, confirming that mixing of the disinfectant water and salt water could be sufficiently suppressed.

In the bathtub purification device of the above embodiment, the device is configured to selectively operate between bathroom spray mode and pooled water sterilization mode, but this is not limited to this. The bathtub purification device of the present invention may operate in succession between bathroom spray mode and pooled water sterilization mode, or may operate both modes simultaneously. For example, by providing two discharge paths for sterilized water from the electrolytic cell or by providing two electrolytic cells, both modes can be operated simultaneously.

In addition, while the above embodiment has been described with reference to an example in which a straightening plate is used as the swirling flow generating means, this is not limited to this, and any means capable of generating a swirling flow can be used in the present invention. For example, a swirling flow can be generated by a rotary drive means such as a screw, or by arranging an outlet 32 for introducing brine into the electrolytic cell 3 in the circumferential direction (the swirling direction) on the outer periphery of the bottom surface of the electrolytic cell 3, and discharging brine from the outlet 32 to generate a swirling flow.

The bathroom purification device of this invention can be used effectively to disinfect and purify bathrooms, etc.
